Corcoran Group

Here's a breakdown of the top real estate companies in the U.S. that people actually use — both for buying/selling homes with an agent and for browsing listings online.

Keller Williams Realty is the biggest name in the industry — Keller Williams Realty is ranked first on the list with $191.6B in revenue, followed by Century 21 with $129.1B in revenue and Coldwell Banker with $56.2B in revenue. Keller Williams is also popular with agents, especially newer ones, because it offers recognizable brands, local office support, and more structured environments.

🚀 Fast-Growing / Tech-Forward Brokerages

If you value technology, flexibility, or you're an agent looking for higher commission splits, these are the ones to know:

• eXp Realty & Real Broker — Both are known for appealing to agents looking for higher splits, lower overhead, revenue share, or long-term incentive models, though higher earning potential often comes with more responsibility.
• Compass — A technology-driven platform that integrates top agents, marketing solutions, and exclusive property price access. Popular in major metro markets.
• REAL (The Real Brokerage) — A newer disruptor; a relative newcomer that has quickly grown its footprint in markets traditionally dominated by more established brokerages, especially known for technology tools like mobile platforms for working on the go, and leveraging automation and AI to streamline processes.
• Realty ONE Group — A leading real estate brokerage with over 20,000 agents in more than 450 offices across 49 U.S. states and over 24 countries.

Corcoran Group — Started in NYC and now a nationwide luxury brand: founded by Barbara Corcoran, this boutique real estate company has become an international franchise, offering a strong name, full suite of marketing tools, and listings on Corcoran.com with almost 50 million views annually.

📱 Platforms Most Consumers Actually Use to Search

• Redfin – known for its own discount-brokerage agents plus listing search
• Realtor.com – official

The residential real estate market in the United States is highly competitive, dominated by massive national franchise networks, tech-forward independent brokerages, and massive real estate tech databases that consumers use daily. In the residential sector, the "best" company often depends on whether you are measuring by raw sales volume, sheer agent count, or consumer website traffic.

The industry has undergone massive corporate consolidation, with major shifts reshaping the landscape of who owns your local real estate brand.

1. The Top Brands by Sales Volume & Scale

These are the massive national brokerages that handle the highest monetary volume of transactions and the most home listings across the country.

Compass: Ranked as the #1 residential brokerage in the United States by sales volume. Compass operates as a tech-enabled premium brokerage. In a historic industry shakeup, Compass completed its acquisition of Anywhere Real Estate, bringing legacy powerhouses like Coldwell Banker, Century 21, Sotheby's International Realty, and Corcoran Group under its massive corporate umbrella. Keller Williams Realty (KW): Consistently the #1 real estate franchise in the U.S. by agent count and transaction sides. KW operates a massive traditional franchise footprint with an agent-centric training model. eXp Realty: A rapidly growing, cloud-based virtual brokerage that ranks among the top companies for transaction sides. It operates completely online without traditional brick-and-mortar offices, using an attractive agent revenue-sharing model. HomeServices of America: A Berkshire Hathaway affiliate that ranks as one of the largest multi-brand real estate enterprises in the nation. It operates a vast network of traditional local brands, including Berkshire Hathaway HomeServices. The Real Brokerage: A fast-growing tech brokerage that recently surged into the top tier of national players. Highlighting the rapid contraction of the market, The Real Brokerage moved to acquire RE/MAX Holdings, absorbing another historically dominant global real estate brand.

3. The Real Estate Products People Actually Use (Online Apps)

When everyday Americans talk about "using" a real estate company, they are usually referring to the tech platforms and property search applications they browse on their phones.

Zillow: The undisputed powerhouse database of online U.S. real estate. It handles over 230 million page views per month—nearly double its closest competitor. Consumers widely use it for its map-based browsing interface and its automated "Zestimate" home valuation tool. Realtor.com: The second most popular home search platform in the U.S.. It pulls data directly from regional Multi-Listing Services (MLS), making it highly trusted by active buyers for accurate, real-time inventory updates. Redfin: Beyond operating as a brokerage with discounted listing fees, Redfin's map-centric consumer application is one of the most visited property search platforms in the country. Homes.com: A massive listing search site owned by CoStar Group that has heavily expanded its footprint to compete directly with Zillow for consumer traffic and agent advertising.
